Journal January 6, 2014 New 300 watt LED grow light

Surfing eBay two weeks ago I came across a new 300 LED grow light that was almost half the cost of the light I purchased a few years ago direct from the manufacturer in China.  And, the light was located in the United States, with free shipping.  Shipping from China was always an issue, with an average cost of sixty dollars on top of the cost of the light.

Although I did not really need another light, the price was attractive, and I could always use a spare, so I made an offer.  The new light arrived today and I placed it in one of the tents to try it.

At the height shown in the photo I measured slightly more than 3,000 foot candles at the top of the canopy.  Measuring the level outside the perimeter of the light case, I found that it has a very nice dispersion all around the case.

When dealing with this type of grow light, foot candles really only serve as a measure of intensity, not effectiveness.  The spectrum is equally, or more, important than intensity.
